HOLDER AND GAGE FOR PAPER CONES WHILE WATERPROOFING THEM.

SPECIFICATION forming part of Letters Patent No. 371,990, dated October 25, 1887;

Application filed May 20, 1886. Serial No. 202,829. (No model.)

To all whom it may concern:

Be it known that L-Milnvin O. STONE, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Holders and Gages for Paper Cones while WVaterprooiing Them, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to devices and a method by which I can rapidly subject paper cones to the act-ion of a material for hardening or otherwise affecting them, and by which I can gage them accurately, so as to have them all treated alike, and can effectually remove from them the surplus material, so as to have their surfaces, both inside and out, smooth and finished.

Figure l is a side view of a mechanism adapted to attain the objects at which I aim. Fig.2 is a top View of a part thereof. Fig. 3 shows some of the details in-end view. Figs. 4c, 5, 6, 7, and 8 show modified forms of the devices,- they being especially adapted for hand operation.

In the drawings, A represents a holder adapted to receivoand support the paper cones E. The latter are conical or frustoconical in shape, they being made by wrapping paper in folds or layers, as shown in section in Fig. 5; but these features of their construction have been made the subj cot-matter of other applications, and do not relate, essentially,to the pres ent one.

In the devices shown in Fig. 1 the holders A are provided with apertures a, of such diameter that the cones E can pass through them to a limited distance only, the upper ends of the cones engaging with the walls or edges of the apertures a, which edges, in this construction, act as supports for them. The holders A are here shown as being supported by chains 0,. which travel on wheels D 1), whereby the chains and the holders A are propelled, and are guided down toward and up and away from avat orvessel, B, wherein is placed the parafiine or other materials,to the action of which the cones are to be subjected. This material or composition of materials is heated by any suitable means, so as to be kept in a liquid condition.

The paper cones E are inserted at 0, Fig. 1, into the apertures a, the holders A traveling in the direction of arrow 1. The cones can be pressed down by hand, or a presser-roller, as at F, can be applied, so as to insure that all of the cones shall be held uniformly. It will be seen that the parts which carry and guide them are so constructed and related that the cones are all gaged alike and pass down into the material at N to a uniform distance, so that after the treatmentiscompleted thecones areallsimilar in appearance. Thisisin contradistinctiou to the method ordinarily employed .in treating such articles, in which they are entirely immersed or submerged in the material in the vat. An important matter in treating these paper cones is the removing of the unneces sary wax or paraffine which adheres to them as they leave the vat. Under some conditions the lower ends of some of the cones will be entirely filled or considerably obstructed, and in very many cases lumps or globules are left adhering to the surface.

One of the important features of this invention is to provide a mode of rapidly'removing the surplus material, so that all of the cones shall be smoothly and uniformly coated and shall be free from obstruction in the interior.

This is done by imparting to the holders A, successively, sharp blows or jerks while the material is still more or less liquid and before it hardens.

G represents a lover or shaker adapted to impart blows or quick upward movements to the holders A as they rise out of the vat. It can be operated in any suitable way--as, for instance, by a cam-wheel, 9', arranged to rock the levershaft g, and a spring, 9", which re turns the lever. After being thus cleaned and made smooth by this jerking or shaking action the cones E are retained in the holders A a sufficient time to allow them to cool, whereupon the holders are inverted and the cones are then knocked out, blows or shakes being imparted, if necessary. At II there is a knocker on shaft h, intermittingly raised by a cam-wheel, h, the knocker being adapted to hit each of the holders A as it moves along, it thereby dislodging the cones E into a receptacle at I.

In Fig. 4 I have shown, in connection with a vat, B, a holder and gage, A, adapted to be operated by hand, but in such way as to per mit the following of the same method as that above described. The holder here is a circular plate carrying a handle, K, by which it can be easily manipulated. Legs or supports D can be combined with the holder, and they can be so constructed as to have it adj nstable, as shown.

In operation the holder is first supported upon atable and is charged with the cones, and it is afterward inserted into the vat, as shown in Fig. 4. After the cones have been immersed a proper time the holder or gage is withdrawn, and is subjected to blows or jerks to attain the ends above set forth.

It is not necessary to use perforations in the holder A in order to properly gage the cones, as they may be secured to it in any efficient manner. Thusin Fig.5 both pins and springs a are shown, which I use interchangeably under some circumstances. for this purpose. When employed,the holder A is first inverted upon a table, P, as in Fig. 5, and is charged with cones E, after which it is turned over and ining and galvanizing and do not claim anything therein disclosed; but my invention differs radically from anything therein found, both in regardvto its mode of operation and the results attained in the carrying of it out. In both those earlier inventions the articles to be treated are to be coated with metal or plated throughout their entire extent of surface. Consequently the depth of their immersion in the liquid is immaterial, except that it is es- 7 sential in order to operate successfully,that the screws or bolts should be entirely covered by the material. On the'contrary, it is indispensable in paraffining my paper cones that some provision shall exist by which a portion of each cone shall be kept from contact with the paraftine; that, in fact, only a portion of each cone, and that the smaller end, shall be inserted in the liquid. It is further very important,in the working of my invention,that some provision shall be made whereby the operator can quickly and accurately gage the depth of immersion of each and every cone. This result I attain by so relating the sizes of the holes or of the pins or springs to the sizes and forms of the paper cones and to the gaging devices that the required depth of immersion shall be secured with great uniformity. Under some circumstances, however, I may dispense with the gages. For instance, when using the construction shown in Figs. 1,4, 7, and 8, thecarriers or holders may be so manipulated that their lower surfaces shall be moved into close proximity through the 'upper surface of the melted paraffine, the depth to which the cones are immersed being governed in such case by the sizes of the holes in the carrier,which will determine the depth or distance to which the cones will project below its lower surface into the 'liquid. Another im.- portant difference between my invention and those which have preceded it is this: In none of the prior ones was there any provision for such frictional contact between the carriers or holders and the articles to be plated that they could be shaken or jarred somewhat violently after immersion without separation, it being apparent from a casual examination of those patents that the screws, bolts, orother articles were suspended loosely by their heads, whereas in working my invention each cone is held firmly in position by reason of the engagement of its tapering sides with either the springs, the pins, or the walls of the holes of the carrier or holder, the points of engagement being intermediate of the ends of the cones.

What I claim is- 1. The combination, with the cones E, of a holder engaging with the tapering sides of the cones at points intermediate of their ends and adapted ,to support said cones by frictional contact, substantially as set forth.

2. The combination, with the cones E E, of a holder provided with openings adapted to engage with the outer surfaces of the cones at points intermediate of their ends, whereby the cones are supported by frictional contact with the holder, their ends projecting on opposite sides thereof, substantially as set forth.

3. The herein-described improvement in the of the holder against the walls of the'cones,

arranging the smallerends of the cones in the same plane, then inserting them allsimultaneously into the parafline, whereby the extent of paraflining can be gaged while the holder is supported in a horizontal position, the larger ends being withheld from contact with the material, substantially as set forth.

4. The herein-described improvement in the art of paraffining paper cones, it consisting in attachingthe cones separately from each other to a holder, securing each cone in place by means of a frictional contact of the holder against the wall of the cone at points distant from the ends of the cone, then inserting the small end of the cone into the paraffiue and causing the latter to rise relatively both inside and outside of the said small end to a predetermined point, the-larger ends being withheld. from contact with the material, substan- In testimony whereof I affix my signature in I0 tially as set forth. presence of two witnesses.
